87-982 10mm Dia. UVFS Aspheric Lens; EFL=10mm; NA=0.5 UV-VIS 250-700nm

The 87-982 is a high-quality aspheric lens, sourced from Edmund Optics, boasting a 10mm diameter and a numerical aperture (NA) of 0.5. This lens is designed for use in the ultraviolet to visible (UV-VIS) spectrum, specifically between 250 and 700 nanometers.

The lens is constructed from UV fused silica, a material with a high transmission rate in the UV and VIS regions, making it ideal for applications that require clear, undistorted images in these wavelengths. The aspheric design of the lens helps to correct spherical aberration, a common issue in traditional spherical lenses, which can lead to distorted images and reduced image quality.

The lens has an effective focal length (EFL) of 10mm, which is the distance from the lens's principal point to its focal point. This EFL makes the lens suitable for use in compact optical systems where space is at a premium. The lens also features a thickness of 2.77mm at the edge and 6mm at the center, providing structural integrity and resistance to deformation.

The lens is coated with a standard UV-VIS coating, which enhances its transmission in the UV and VIS regions, reducing reflection and increasing the amount of light that passes through the lens. This coating is applied to both the front and back surfaces of the lens, ensuring optimal performance from all angles.
